WGU D482 SECURE NETWORK DESIGN TASK 1
2026 REVISION NOTES AND STRUCTURED
CYBERSECURITY DESIGN OVERVIEW GUIDE
◉ Design Phase (SDLC). Answer: Requirements are prepared for the
technical design
◉ Implementation Phase. Answer: The resources involved in the
application from a known resource are determined
◉ Maintenance Phase. Answer: Ongoing security monitoring is
implemented
◉ Planning Phase of SDLC. Answer: vision and next steps are created
◉ secure code. Answer: a principle design in coding that refers to
code security best practices, safeguards, and protection against
vulnerabilities
◉ threat modeling. Answer: a structured process to protect against
vulnerabilities
,◉ What are the three core elements of security. Answer:
confidentiality, integrity, and availability
◉ 8 phases of the SDLC. Answer: planning, requirements, design,
implementation, testing, deployment, maintenance and end of life
◉ What is software security. Answer: Security that deals with
securing the foundational programmatic logic of the underlying
software
◉ Which part of the CIA keeps unauthorized users from accessing
confidential information. Answer: Confidentiality
◉ BSIMM. Answer: a study of real-world software security that
allows you to develop your software security over time
◉ dynamic analysis. Answer: analysis of computer software that is
performed when executing the program on a real or virtual
processor in real time
◉ fuzz testing. Answer: automated or semi-automated testing that
provides invalid, unexpected, or random data to the computer
program.
, ◉ measure model. Answer: A set of data security methods that
developers take to protect against vulnerabilities
◉ metric model. Answer: allows organizations to determine the
effectiveness of their security controls
◉ OWASP. Answer: A flexible and prospective framework to build
security into your software development organization
◉ static analysis. Answer: The analysis of computer software that is
performed without executing programs
◉ Computer Vulnerabilities and Exposures. Answer: A list of
information that aims to provide common names for publicly known
security vulnerabilities
◉ What are the three primary tools basic to the SDLC. Answer: Fuzz
testing, static analysis, and dynamic analysis testing
◉ In which phase of the SDLC should the software security team be
involved. Answer: Concept
